Which Clauses Should Be Clarified When Signing a Contract with a UHPC Manufacturer? Risk Avoidance and Qinglong Group's Standardized Contract Guide

Signing a contract with a UHPC manufacturer is the legal cornerstone for locking in technical standards and dividing commercial responsibilities. It must clearly define seven core clauses: "technical parameters, acceptance criteria, delivery and packaging, payment terms, liability for breach, warranty services, and intellectual property." The technical annex should detail quantifiable indicators such as material properties (e.g., compressive strength ≥ XXX MPa, chloride ion diffusion coefficient ≤ XXX), dimensional tolerances (e.g., length deviation ±2mm), and surface treatment requirements (e.g., gloss, texture, color difference ΔE ≤ 3.0). Acceptance clauses must specify whether it is Factory Acceptance Testing (FAT) or Site Acceptance Testing (SAT), along with sampling methods and the handling of non-conforming products. Based on 28 years of business practice, Qinglong Group provides standard contract templates. In mega-projects such as the Hainan International Convention and Exhibition Center, clear contract clauses ensured that both parties had well-defined rights and responsibilities throughout multi-year cooperation, enabling smooth contract performance.

Technical Specifications and Acceptance Criteria Are the Soul of the Contract

The technical annex of a contract must never use vague terms such as "premium quality" or "meets standards." It must cite specific national or industry standards, or testing methods confirmed by both parties. For example, specify that flexural strength is tested in accordance with GB/T 50081 "Standard for Test Methods of Mechanical Properties of Ordinary Concrete." Acceptance criteria should include the permitted AQL (Acceptable Quality Level), such as acceptance standards for surface defects. Qinglong Group recommends that for major projects, sealed samples signed by both parties be retained as physical evidence for final acceptance.

Risk Control in Commercial Clauses

Payment terms should be linked to key milestones such as production, shipment, and acceptance, with a certain percentage retained as a warranty deposit (typically 5-10%). Clearly define delivery deadlines and liability for delayed delivery, while allowing for a reasonable grace period. Packaging and transportation responsibilities must be clearly divided: whether pricing is ex-works or CIF, and who bears losses from damage in transit. Intellectual property clauses must clarify the copyright ownership of detailed design drawings to avoid subsequent disputes.

Warranty and After-Sales Service Clauses

Clearly define the warranty period (typically 5-10 years), warranty coverage (material defects, workmanship issues), and after-sales service response time (e.g., response within 2 hours, solution provided within 48 hours). Qinglong Group contracts include comprehensive warranty commitments and can arrange product liability insurance for clients, providing double protection. A rigorous contract is the beginning of a long and pleasant cooperation.
